<p>Well, I signed up for the May and June SAT subject tests already. I'm planning to take one Math IIC in May and Chemistry in June. </p>
<p>But I think I want to take 3 SAT subject tests instead of 2 because I might consider applying to John Hopkins. </p>
<p>Is there any way I can add another test on the May or June test date?</p>
<p>just go on collegeboard and register for another. you can take up to 3 each time, so it shouldn't be a problem.</p>
<p>I can't. It won't let me. I already Registered for May and June. </p>
<p>This is what it says when I press "register for a test" It says. "There are no available registration dates for the current test year. Please check back later for future tests."</p>
<p>Try to find where you can change the status of your previous registrations. There, you will find a fee for changing the test date or center. You could probably add another test; for an additional fee, however.</p>
<p>You don't even have to register online for it. On the day itself, just take all three and notify the person in charge. College board will bill you accordingly. :)</p>
<p>Yeah, I also read this one on their website after i finished my Subject SAT registration.</p>
<p>ok. thanks.</p>
<p>Confirmed. I've done it before. The amount just gets debited from your card automatically.</p>
<p>so if I sign up for one Subject test and on the day I ask for two and tell them about it, they will just bill the two and not the late fee?</p>
<p>I think you can just call their office and ask them if you can add a test and they'll do it for you.</p>
